Title: Improvements relating to water demineralizing units particularly for domestic supplysystems
IPC: C02F1/46
Filed: 1956-05-11
Abstract: 809,685. Softening water; ion-exchange apparatus. GENERAL ELECTRIC CO. May 11, 1956 [May 12, 1955 ; June 29, 1955], No. 14731/56. Class 46. [Also in Groups XI and XXXVI]. Water intended for a domestic supply system and derived from a hard-water source is passed at 93 into a perforated distribution ring 96 and falls thence on to a bed of mixed ion-exchange resins occupying an annular chamber 32 lying between inner and outer diaphragms 31 and 29 respectively. Demineralized water emerges into a lower compartment 28 whence the bulk passes out at 103, while a minor proportion passes through a check valve 111 and upwards between the diaphragm 31 and an anode 33 (thus forming the anolyte), and a further minor proportion passes through a check valve 109 and upwards between the diaphragm 29 and the casing 11 constituting the earthed cathode (thus forming the catholyte). The demineralization is performed mainly by ion-exchange and to a less extent by electrodialysis. During the time that water is not being withdrawn from the apparatus the ion-exchange bed is being regenerated by electrolytically-produced hydrogen and hydroxyl ions while cations and anions previously present in the raw water are conveyed by electrodialysis from the resins into the catholyte moving upwards in the catholyte chamber 30 and into the anolyte moving upwards in the anolyte chamber 34 respectively. These liquids meet at the top of a cylindrical baffle 87 between the anode 33 and a dome 49, 53 and flow downwards into a mixing chamber 116, whence they leave the apparatus at 114. Small amounts of oxygen and hydrogen evolved at the anode and cathode respectively pass upwards into an upper dome section 50 where they combine harmlessly in the presence of a mass of catalyst 118 contained in a bag. The diaphragm 29 comprises a perforated outer sleeve of mild steel and two inner sleeves, e.g. of wood, preferably poplar ; the outer sleeve is coated with insulating material. The diaphragm 31 comprises a perforated inner sleeve of, e.g. thermoplastic resin and an outer sleeve, e.g. of wood, preferably poplar. The D.C. potential maintained between the anode and cathode may be provided by an A.C source and rectifier, the A.C. source also providing current for electric heating elements on the outside of a water storage tank through which the demineralized water passes on its way to use (see Group XI). Reference has been directed by the Comptroller to Specification 776,469 [Group XXXVI].

Title: Improvements in and relating to the delivery of cigarettes and the like
IPC: A24C5/32
Filed: 1933-05-22
Abstract: 420,158. Cigarette-making machines. CHANDLER, R. J. A., 58, Holborn Viaduct, London. May 22, 1933, No. 14782. [Class 130] In mechanism for collecting cigarettes &c. from a continuous-rod machine, in which a rotary element such as a vaned drum 7 delivers the cigarettes transversely from a conveyer belt 6 to a transfer device 16 which delivers them to a collector belt 20, a gripping or brake device 14 tends to oppose the transverse movement, so that the cigarettes are under the influence of the element 7 until they are received by the transfer device. In one form, the drum 7 is provided with vanes 8 in two sets separated by stops 11 against which alternate cigarettes abut, the remaining cigarettes being stopped by a flange on the drum or a stationary fence. The cigarettes on the belt 6 are aligned axially by the edge of a plate 9 and are delivered by the vanes 8 over the curved edge of a table 13, under the control of the brake springs 14, to pairs of fluted transfer wheels 16, from which they are delivered by slotted plates 21 to the collector belt 20. The plates 21 may have an open central portion through which short cigarettes fall down a guide 22 into a receptacle 23. In a modification, the plates 21 are omitted and the collector belts pass around drums coaxial with the transfer wheels 16. The drums may be driven at the same speed as the wheels 16, or may be freely rotatable, the collector belt being driven more slowly than the wheels. The fluted wheels may be replaced by a grooved drum and the cigarettes may be retained in the flutes or grooves by a stationary guide and delivered at the bottom of the wheels or drum.

Title: Method of and apparatus for sonar signal texture enhancement
IPC: G01S7/60
Filed: 1975-04-14
Abstract: 1507177 Sonar KLEIN ASSOCIATES Inc 14 April 1975 [4 Nov 1974] 15207/75 Heading. G1G The Specification describes a system for enhancing the quality of received sonar or similar signals which are to be displayed and recorded in a recording means having a dynamic range capability substantially less than that of the received signals. A logarithmically compressed, amplified form of the sonar echo signal is smoothed and the derivative thereof is obtained which signal is applied to the recording means to substantially match the dynamic range thereof. As described, pulses are transmitted from a transducer (8), Fig.1 (not shown) and received echoes are filtered and amplified and transmitted back to a ship via a tow cable which is towing the sonar TX/RX apparatus. The echo signals are applied to an amplifier 14' Fig. 3 which comprises an operational amplifier A1 having back-to-back diodes CR1 CR2 in the feedback loop thereof whereby logarithmic compression of the echo signals is obtained. The signals are then full wave rectified by circuit 5 and integrated by capacitors C1 and C2. The resulting smoothed absolute value signal which represents the envelope of the received signals is then differentiated at 7 and applied to print amplifier 22 which drives the recording mechanism 10 which may be a drum recorder. It is stated that the aforementioned circuitry matches the dynamic range of the echo signal, e. g. 120dB to that of the recording mechanism e. g. 20-40dB. Modifications are described wherein the rectifier output is made to be negative going whereupon increasing, echo signal magnitude will be recorded as a whiter signal; a diode CR5 may be included in differentiator 7 to allow output signals therefrom of one polarity only.

Title: Improvements in hydraulic distant-control apparatus
IPC: F15B11/22
Filed: 1924-06-24
Abstract: 218,993. Schneider et Cie. July 11, 1923, [Convention date]. Naval mountings. -Relates to hydraulic distant-control apparatus, particularlv applicable for laying naval guns, and consists in providing at the central station a pressure system produced by a pump P and accumulator A and controlled by a distributing valve D so as to operate synchronously a hydraulic motor M<1> for moving the sight and one or more hydraulic motors M<2>, M<3> for laying the guns. Each motor receives from the central station the same volume of liquid and the necessary corrections are applied by the gun layers to the gun motors by means of compensating pumps C<2>, C<3> operated by irreversible gearing T<2>, T<3>. The motors M<2>, M<3> are fed in by-pass from the distributor to render them independent of one another, their synchronism being assured by auxiliary motors S<1>, S<2>, S<3> fed in series from the main motors and coupled to a common shaft. Fig. 3 shows gear for automatically stopping the gun motors when extreme laying positions are reached. This is effected by a cam on the gun mounting which engages a tappet I to open a valve Z. To bring the gun motor into operation again, a lever U is actuated in the direction of the arrow against the action of a spring B to close the valves K, L and permit of moving the motor M<2> by actuating the pump C<2>. This brings the gun on to the target again, the valve Z being held open by the hook W. On releasing the handle U normal working is resumed. To ensure the passage of liquid in both directions if one of the motors is accidentally blocked, a valve Z<1> opening in the opposite direction to the valve Z is provided. The main and compensating pressure systems P, C<2>, C<3> may be replaced by a constant-speed electric motor driving a variable-delivery pump. The compensating pumps C<2>, C<3> may be replaced by mechanical differential gearing.

Abstract: 1,040,961. Tractor power lift mechanisms. MASSEY-FERGUSON. April 19, 1963 [April 25, 1962], No. 15443/63. Heading A1P. A tractor hydraulic control system incorporating automatic draft control has a feedback device 150 to dampen the effect of the draft control mechanism under momentary differences of load. The lower links 19 of the hitch linkage are pivoted on an arm 27 (Fig. 1, not shown) to impart longitudinal movement to a frame 25 against a spring bias 30. A stop 141 on the frame 25 operates a bell crank 139 which is connected through a linkage with a further bell crank 123 which serves to control, through a link 127 and a pivoted arm 83, the main control valve 50. The feed-back device 150 consists of a piston 153 (Fig. 4, not shown), operated against a spring bias 157 by a momentary increase in draft load which raises the fluid pressure in the cylinder 39 and therefore in the conduits 102, 165. The piston operates to move the link 127 about its pivot whereby, since the base of the link has a cam surface 176, the effective length of the link is shortened and the valve 50 is thus moved in a direction to neutralize the effect of the draft control. The operation of the valve 50 and of the position control arrangement is similar to that described in Specification 1,046,621 except that two separate levers are used to operate the position and draft controls.
